Chemical structure of 1245645-20-8, CAS 1245645-20-8
Structure as published in the WesynTech product centre.
pyridine heterocycleBoc-protected

CAS 1245645-20-8 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 pyridine heterocycle chemistry — the most-used nitrogen heterocycle in medicinal chemistry, and one of the fussiest to substitute selectively. 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.

Supply

How this gets made and delivered

CAS 1245645-20-8 is supplied on the same terms as the rest of the catalogue. Delivery quantities are agreed per enquiry rather than fixed in a price list. Laboratory batches come from the Shanghai site; larger requirements are run in the pilot plant, whose −70 °C to 200 °C window means neither cryogenic steps nor high-temperature ones force the work off site; industrial volumes go to partner plants on the same route.

  • 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 1245645-20-8

What quantity of CAS 1245645-20-8 can WesynTech supply?

Quantities for CAS 1245645-20-8 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.

What specification and analytical data come with CAS 1245645-20-8?

The former wesyntech.com site published no specification for CAS 1245645-20-8 (CAS 1245645-20-8), 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 1245645-20-8 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 1245645-20-8 as the nearest listed match, and the team will assess that route.
