CAS 429673-82-5 · Catalogue Building Blocks · (3S,4S)-tert-butyl 3-(tert-butoxycarbonyl(Methyl)aMino)-4-hydroxypyrrolidine-1-carboxylate
CAS 429673-82-5 sits in WesynTech's general catalogue of privileged building blocks — small, functionalised structures that turn up across unrelated programmes and are worth keeping available rather than commissioning each time.
The structure is pyrrolidine / pyrrole heterocycle chemistry — saturated nitrogen character in a compact ring. It carries defined stereochemistry, which is one of the four areas (chiral compounds, fluorine, boronates, heterocycles) where WesynTech has concentrated its synthetic work. It arrives Boc-protected, so the reactive position is held until you want it. Synthetically it offers a carboxylic acid or ester position for amidation, reduction or further homologation; a free amine for acylation, reductive amination or coupling; a hydroxyl for etherification, oxidation or activation.

Supply
How this gets made and delivered
CAS 429673-82-5 is supplied on the same terms as the rest of the catalogue. Scale is the part buyers usually want pinned down first. Custom synthesis capability here runs from gram to hundred-kilogram, which covers a first sample, a repeat order and a modest campaign without a change of supplier. Above that, long-term partner plants take the volume using the route already proved in-house.
- Laboratory quantities from the Shanghai site, close to 600 m² of laboratory space.
- Pilot plant: two 20 L single-layer reactors, six 50 L double-layer reactors at −70 °C to 200 °C, four 50 L rotary evaporators.
- Industrial volumes through long-term partnerships with several chemical plants for industrial-scale production.
Questions about 429673-82-5
What quantity of CAS 429673-82-5 can WesynTech supply?
Quantities for CAS 429673-82-5 are quoted per enquiry rather than listed. In-house capability is stated from gram to hundred-kilogram scale, with larger industrial volumes produced through long-term partner plants using the same route.
Is the stereochemistry of CAS 429673-82-5 confirmed on each batch?
The analytical package applied to CAS 429673-82-5 is agreed per project. Chiral synthesis is one of WesynTech's four stated areas of technical strength, and the specific checks run on a batch of this compound are confirmed with the quotation.
What specification and analytical data come with CAS 429673-82-5?
The former wesyntech.com site published no specification for CAS 429673-82-5 (CAS 429673-82-5), and none is invented here. Purity, appearance, packaging and the available analytical package are confirmed in writing with the quotation.
Can you make a close analogue of CAS 429673-82-5 rather than this exact compound?
Yes — that is what the custom synthesis service is for. Send the analogue you actually want instead of accepting CAS 429673-82-5 as the nearest listed match, and the team will assess that route.
