Chemical Structure

2H-Azepin-2-one, hexahydro-, polymer with 1,1'-methylenebis[4-isocyanatobenzene] and 2,2,4-trimethyl-1,3-pentanediol CAS 67846-29-1 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 2H-Azepin-2-one, hexahydro-, polymer with 1,1'-methylenebis[4-isocyanatobenzene] and 2,2,4-trimethyl-1,3-pentanediol.

CATO supplies 2H-Azepin-2-one, hexahydro-, polymer with 1,1'-methylenebis[4-isocyanatobenzene] and 2,2,4-trimethyl-1,3-pentanediol (CAS 67846-29-1), a certified reference material (molecular formula C15H10N2O2C8H18O2C6H11NO, MW 509.65 g/mol) for analytical method development and quality control.

Structurally, 2H-Azepin-2-one, hexahydro-, polymer with 1,1'-methylenebis[4-isocyanatobenzene] and 2,2,4-trimethyl-1,3-pentanediol (C15H10N2O2C8H18O2C6H11NO) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 509.65 g/mol, it falls into the moderately-high-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

As a certified reference material (CRM), 2H-Azepin-2-one, hexahydro-, polymer with 1,1'-methylenebis[4-isocyanatobenzene] and 2,2,4-trimethyl-1,3-pentanediol 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.
