3-Acetoxy-11-ursen-28,13-olide 35959-08-1 C32H48O4 W2585 CAS 35959-08-1 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-Acetoxy-11-ursen-28,13-olide 35959-08-1 C32H48O4 W2585.

CATO supplies 3-Acetoxy-11-ursen-28,13-olide 35959-08-1 C32H48O4 W2585 (CAS 35959-08-1), a certified reference material (molecular formula C32H48O4, MW 496.72 g/mol) for analytical method development and quality control.

Structurally, 3-Acetoxy-11-ursen-28,13-olide 35959-08-1 C32H48O4 W2585 (C32H48O4) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 496.72 g/mol, it falls into the moderately-high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

As a certified reference material (CRM), 3-Acetoxy-11-ursen-28,13-olide 35959-08-1 C32H48O4 W2585 meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
