(R)-(+)-3-Chloro-1-phenylpropan-1-ol | CAS 100306-33-0

A chiral benzylic alcohol with a terminal covalent chloride, referenced as a building block for aryloxypropylamine and chroman chemistry, where R identity and the intact chloropropanol framework matter together.

CAS100306-33-0
Molecular formulaC9H11ClO

Product overview

The three-carbon chain of this R-configured building block carries a benzylic alcohol at one end and a covalent chloride at the other. CAS 100306-33-0 identifies the neutral alcohol, with the full chloropropanol connectivity retained. Described applications include enantiomeric antidepressant and chroman synthesis. For route selection, assess the R alcohol configuration together with both functional-group positions. Chemical assay and enantiomeric composition should be reported separately, while structural identification confirms the alcohol and terminal chloride. If optical rotation is used, record the solvent, concentration and temperature with the result.

Application context

This R-configured chlorophenylpropanol has been described as a building block for enantiomeric tomoxetine, nisoxetine and fluoxetine chemistry, and for 2-substituted chromans. It combines a benzylic alcohol with a terminal carbon–chlorine bond on a three-carbon chain. Compare the target sequence and its stereochemical requirements with this starting structure. Assess R/S composition, alcohol identity and terminal chloride together when defining sample acceptance.

Chemistry and synthetic role

The alcohol-bearing carbon is stereogenic and designated R. Chlorine is bonded to the terminal carbon rather than supplied as a counterion; changing that functionality produces a different synthetic fragment.

Quality review

Separate R identity from rotation sign

Specify the chiral criterion; if rotation is used, require its solvent, concentration and temperature.

Confirm the chloropropanol framework

Use structural evidence for both the benzylic alcohol and terminal chloride.

Review chemistry and chirality separately

Agree chemical assay and enantiomeric composition as separate results relevant to the selected route.

Preparing a specification

Request the R alcohol under CAS 100306-33-0, with the terminal chloride intact. State chemical assay, chiral method and acceptance criteria; include optical-rotation conditions only where that test is part of the agreed qualification.

Packaging and storage

Confirm packaging format, net weight and transport arrangements for the selected grade, quantity and destination. Agree storage and handling conditions using the actual supplied material’s SDS and label.

Documentation

Request identity spectra, chemical and chiral chromatograms, COA and SDS. Confirm how any reported rotation was measured and how the proposed analytical method distinguishes relevant related compounds.

Procurement questions

Does the chlorine indicate a hydrochloride?

No. It is a covalent terminal C–Cl bond in a neutral alcohol.

Does R automatically specify the final drug configuration?

No. The stereochemical consequences depend on the actual sequence of transformations.

Which identity checks should accompany the chiral result?

Confirm the benzylic alcohol, three-carbon chain and terminal covalent chloride as well as the R/S composition.
