Chemical Structure

Travoprost Impurity 19 CAS 37435-69-1 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 140.11 g/mol gives Travoprost Impurity 19 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Travoprost Impurity 19 (CAS 37435-69-1), a pharmacopoeial impurity reference standard (molecular formula C5H9O3Na, MW 140.11 g/mol) used for the identification and quantification of trace impurities in APIs.

Structurally, Travoprost Impurity 19 (C5H9O3Na) contains a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 1.5, corresponding to approximately 1 ring(s) or double-bond equivalent(s). With a molecular weight of 140.11 g/mol, it falls into the low-molecular-weight range.

Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.

CATO manufactures Travoprost Impurity 19 under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
