565460-15-3 Biphenyl-3-yl Carbamic Acid, Cyclohexyl Ester N-[1,1'-Biphenyl]-3-yl-carbamic Acid Cyclohexyl Ester URB602 [1,1 inverted exclamation mark -Biphenyl]-3-yl-carbamic acid cyclohexyl ester [1,1'-Biphenyl]-3-yl-carbamic acid cyclohexyl ester CAS 565460-15-3

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 565460-15-3 Biphenyl-3-yl Carbamic Acid, Cyclohexyl Ester N-[1,1'-Biphenyl]-3-yl-carbamic Acid Cyclohexyl Ester URB602 [1,1 inverted exclamation mark -Biphenyl]-3-yl-carbamic acid cyclohexyl ester [1,1'-Biphenyl]-3-yl-carbamic acid cyclohexyl ester.

565460-15-3 Biphenyl-3-yl Carbamic Acid, Cyclohexyl Ester N-[1,1'-Biphenyl]-3-yl-carbamic Acid Cyclohexyl Ester URB602 [1,1 inverted exclamation mark -Biphenyl]-3-yl-carbamic acid cyclohexyl ester [1,1'-Biphenyl]-3-yl-carbamic acid cyclohexyl ester (CAS 565460-15-3), molecular formula C19H21NO2 and molecular weight 295.38 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 565460-15-3 Biphenyl-3-yl Carbamic Acid, Cyclohexyl Ester N-[1,1'-Biphenyl]-3-yl-carbamic Acid Cyclohexyl Ester URB602 [1,1 inverted exclamation mark -Biphenyl]-3-yl-carbamic acid cyclohexyl ester [1,1'-Biphenyl]-3-yl-carbamic acid cyclohexyl ester (C19H21NO2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 295.38 g/mol, it falls into the medium-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.

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.
