从India供应商批量进口Aleuritic Acid ( Chemically Pure)

Aleuritic acid (chemically pure) from Rst Shellac Overseas Pvt. Ltd. is a shellac-derived hydroxy acid with the molecular formula C12H22O4, produced in Raipur, Chhattisgarh, India. The supplier states purity exceeding 99%, though no specific test method (HPLC, GC or titration) or certificate of analysis details are provided in the source. Aleuritic acid is obtained by alkaline hydrolysis of shellac resin, yielding 9,10,16-trihydroxypalmitic acid, a key building block for macrocyclic lactone musk synthesis and polymeric surface-coating formulations.

The chemically pure grade implies minimal shellac wax or pigment residue, but buyers should confirm whether the batch meets pharmacopoeial standards (USP, EP) or reagent-grade specifications (ACS). Typical aleuritic acid appears as an off-white to pale yellow crystalline solid with a melting range of 95-105 degrees Celsius, soluble in hot ethanol and alkaline aqueous media. The source description references use in pharmaceuticals, cosmetics and agrochemicals, yet no specific pharmacopoeia monograph, particle-size distribution or residual-solvent data is listed. Indian shellac production is concentrated in Bihar, Uttar Pradesh and Madhya Pradesh; Chhattisgarh-based processing suggests either raw-shellac import or regional collection infrastructure.

Primary buyers include fragrance houses synthesising ambrettolide and civetone analogues, polymer laboratories preparing polyesters and polyurethanes, and agricultural-formulation companies using aleuritic acid as a biodegradable surfactant intermediate. The source mentions flexible minimum order quantities and letters of credit, but no confirmed figure, price band or lead time is disclosed. Rst Shellac Overseas Pvt. Ltd. should be asked for a material safety data sheet, REACH pre-registration or exemption status, and stability data if the acid is stored above 30 degrees Celsius.

Rst Shellac Overseas Pvt. Ltd. is headquartered at 42 Vardhman Nagar, New Rajender Nagar, Raipur 492001, Chhattisgarh, India. The company is classified as an imported-tier supplier with harbour trust status, and like the first listing, shows a 0.00% response rate and zero average response hours, indicating no recent buyer engagement on the platform. Its specialisation in shellac derivatives suggests upstream access to raw lac or established toll-manufacturing relationships with shellac refiners in central and eastern India.

The supplier profile does not disclose year of incorporation, production capacity, number of employees, revenue, client list, or quality certifications such as ISO 9001 or GMP. The source description references ISO and SGS certifications, but these are attributed generically to the marketplace narrative rather than confirmed as held by Rst Shellac Overseas Pvt. Ltd. itself. Buyers should request copies of actual certificates, scope statements and audit dates before relying on compliance claims.
