Description

Structurally, 751-83-7 (3-Methyl-5-(2,6,6-trimethyl-1-cyclohexen-1-yl)-2,4-pentadienyl)triphenylphosphonium sulphate Phosphonium, (3-methyl-5-(2,6,6-trimethyl-1-cyclohexen-1-yl)-2,4-pentadien-1-yl)triphenyl-, sulfate (1:1) Phosphonium, (3-methyl-5-(2,6,6-trimethyl-1-cyclohexen-1-yl)-2,4-pentadienyl)triphenyl-, sulfate (1:1) EINECS 212-028-2 EC 212-028-2 (C33H38PO4S) contains a sulfone group, a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 15.0, corresponding to approximately 15 ring(s) or double-bond equivalent(s). With a molecular weight of 561.70 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.

751-83-7 (3-Methyl-5-(2,6,6-trimethyl-1-cyclohexen-1-yl)-2,4-pentadienyl)triphenylphosphonium sulphate Phosphonium, (3-methyl-5-(2,6,6-trimethyl-1-cyclohexen-1-yl)-2,4-pentadien-1-yl)triphenyl-, sulfate (1:1) Phosphonium, (3-methyl-5-(2,6,6-trimethyl-1-cyclohexen-1-yl)-2,4-pentadienyl)triphenyl-, sulfate (1:1) EINECS 212-028-2 EC 212-028-2 (CAS 751-83-7) is a high-purity analytical reference standard with the molecular formula C33H38PO4S and a molecular weight of 561.70 g/mol.

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), 751-83-7 (3-Methyl-5-(2,6,6-trimethyl-1-cyclohexen-1-yl)-2,4-pentadienyl)triphenylphosphonium sulphate Phosphonium, (3-methyl-5-(2,6,6-trimethyl-1-cyclohexen-1-yl)-2,4-pentadien-1-yl)triphenyl-, sulfate (1:1) Phosphonium, (3-methyl-5-(2,6,6-trimethyl-1-cyclohexen-1-yl)-2,4-pentadienyl)triphenyl-, sulfate (1:1) EINECS 212-028-2 EC 212-028-2 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.
