Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including R72VB4E4KC 77392-58-6 Paraherquamide BRN 3599562 (-)-Paraherquamide UNII-R72VB4E4KC.

CATO supplies R72VB4E4KC 77392-58-6 Paraherquamide BRN 3599562 (-)-Paraherquamide UNII-R72VB4E4KC (CAS 77392-58-6), a certified reference material (molecular formula C28H35N3O5, MW 493.59 g/mol) for analytical method development and quality control.

Structurally, R72VB4E4KC 77392-58-6 Paraherquamide BRN 3599562 (-)-Paraherquamide UNII-R72VB4E4KC (C28H35N3O5) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 13.0, corresponding to approximately 13 ring(s) or double-bond equivalent(s). With a molecular weight of 493.59 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.

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

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
