Explore our top-performing industrial reagents, custom syntheses, and standardized herbal compounds designed for global pharmaceutical and diagnostic applications.
Bilirubin (specifically **Bilirubin Total** CAS 635-65-4) is a highly critical linear tetrapyrrole pigment derived from the physiological breakdown of heme. Historically considered a metabolic waste product, modern biochemistry has revealed its intense utility as a physiological antioxidant, diagnostic reference standard, and a foundational precursor for complex synthesis. However, scaling manufacturing from laboratory benches to commercial industrial outputs remains a bottleneck for many chemical factories.
As a globally integrated high-tech enterprise, Chengdu Chenlv Herb Co., Ltd. addresses these systemic supply-chain barriers by leveraging advanced botanical extraction systems, chemical isolation techniques, and strict quality control infrastructures. Our macro industry solution is designed to support diagnostic kit developers, active pharmaceutical ingredient (API) manufacturers, and clinical research institutes with highly purified, stable, and cost-effective Bilirubin raw materials.
Traditional isolation methods often depend heavily on chlorinated solvents, leading to environmental compliance issues and toxic residues in final diagnostic applications. Under green chemistry principles, modern extraction facilities are transitioning to aqueous-based extraction cascades combined with HPLC chromatography. This allows for high-yield separation of conjugated and unconjugated fractions without compromising structural stability or regulatory thresholds set by EP, USP, and ChP.
Chengdu Chenlv Herb Co., Ltd. (referred to as "Chenlv Herb") was established in 2012 as a high-tech enterprise specializing in the R&D, production, and sales of botanical extracts and natural pharmaceutical ingredients. Committed to providing high-purity, highly active, and premium-quality natural raw materials, the company serves diverse industries, including pharmaceuticals, health supplements, food, and cosmetics.
By bridging advanced technology and classical extraction methods, we ensure that every batch of botanical extract and organic compound meets high industrial thresholds. With continuous investments in laboratory automation, process engineering, and global logistics systems, we are able to provide scalable solutions for partners in more than a dozen target markets worldwide.

For procurement officers and R&D laboratory directors, selecting a reliable Bilirubin supplier requires assessing strict technical criteria. Below is our typical batch standard specifications sheet.
| Analytical Parameter | Specification Target | Testing Methodology / Reference | Industrial Importance |
|---|---|---|---|
| Assay Purity (HPLC) | ≥ 98.0% (Dry Basis) | HPLC-UV / Chromatographic Integration | Ensures high-precision diagnostic kit calibration. |
| Physical Appearance | Deep Orange-Red to Brownish Crystalline Powder | Visual / Spectroscopic colorimetry | Indicates correct oxidation state and crystalline phase. |
| Solubility Profile | Soluble in Chloroform & Alkaline aqueous buffers | Visual standard dissolution tests | Critical for formulating liquid reagents or test matrices. |
| Loss on Drying | ≤ 2.0% | Thermogravimetric Analysis (105°C, vacuum) | Prevents moisture-induced hydrolytic degradation. |
| Residue on Ignition (Ash) | ≤ 0.1% | Muffle Furnace Ashing (600°C) | Guarantees low inorganic and metal trace contamination. |
| Heavy Metals (Pb, As, Cd, Hg) | ≤ 10 ppm total | ICP-MS (Inductively Coupled Plasma Mass Spec) | Essential for pharmaceutical regulatory clearance. |
Understand the pricing structures and variables that dictate commercial rates in global biochemical manufacturing corridors.
The price of raw Bilirubin is highly volatile, driven by the biological source chain, extraction yield efficiencies, environmental regulatory fees, and GMP certification. Sourcing from non-certified factories can lead to analytical failure, while purchasing from Western standard laboratories can incur significant cost premiums.
*Please note: The following prices are reference estimates based on market conditions. Exact pricing is subject to batch-specific parameters and volume contract lengths.*

Our manufacturing processes are verified to ensure trace-compliance, bio-safety, and international standard certification.
Regulatory frameworks govern botanical and chemical derivatives. Our facilities strictly operate under standardized pharmaceutical protocols to support regulatory dossiers (e.g. DMF filing).
Minimizing lead times through cold-chain logistics, regional warehouse operations, and localized regulatory compliance.
Bilirubin Total is highly susceptible to temperature fluctuations. Our operations feature thermal tracking systems that maintain the shipment between 2°C and 8°C throughout transport. We utilize specialized UV-impenetrable packaging filled with nitrogen to prevent degradation during shipping.
Because Bilirubin can be derived from bovine/porcine origins, customs processes require specific health declarations and non-BSE/TSE documentation. Our logistics team pre-validates paperwork with destination authorities to ensure prompt custom clearance.

An evaluation of next-generation chemical extraction and synthetic developments in the global bilirubin sector.
The industry is undergoing transition. While natural bile extraction remains the dominant commercial source of bilirubin, research into enzyme-catalyzed synthesis and microbial fermentation models is progressing rapidly. These methods aim to deliver highly pure bilirubin without relying on animal supply chains.
Chengdu Chenlv Herb is exploring hybrid processing technologies, combining organic synthesis protocols with traditional botanical chromatography to improve yield consistency. This research helps insulate supply chains from livestock market fluctuations.
Phase I (Process Optimization): Implementing automated column chromatography systems to scale unconjugated compound yields.
Phase II (Regulatory Integration): Extending DMF filings across additional regional regulatory authorities.
Phase III (Biosynthetic Research): Validating enzymatic biocatalysis systems for producing high-grade synthetic bilirubin analogues.
Answers to common technical, logistical, and commercial inquiries regarding our Bilirubin and natural compounds.
Unconjugated (free) Bilirubin is insoluble in water and must bind to albumin for transport. Conjugated Bilirubin has undergone glucuronidation in the liver, rendering it water-soluble. We offer unconjugated versions, typically utilized as reference materials in diagnostic test development.
