RO3
CAS 1026582-88-6 · Active Pharmaceutical Ingredients · 5-[[4,5-Dimethoxy-2-(methylethyl)phenyl]methyl]-2,4-pyrimidinediamine
RO3 (CAS 1026582-88-6) is listed by WesynTech under active pharmaceutical ingredients. Compounds in this group are ordered by name and number rather than by description — a programme asking for this material already knows what it is for, and the supplier's job is to deliver the right substance, identified unambiguously, in the quantity the work needs.
The structure is pyrimidine heterocycle chemistry — a hinge-binding core that appears across kinase and nucleoside chemistry. Synthetically it offers a free amine for acylation, reductive amination or coupling.

Supply
How this gets made and delivered
RO3 is supplied on the same terms as the rest of the catalogue. Small quantities are made and released from the Shanghai laboratory. If the requirement grows, the same route moves into the pilot plant — six 50 L double-layer reactors covering −70 °C to 200 °C, two 20 L single-layer reactors and four 50 L rotary evaporators — rather than being re-developed by someone else.
- 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 RO3
What quantity of RO3 can WesynTech supply?
Quantities for RO3 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 RO3?
The former wesyntech.com site published no specification for RO3 (CAS 1026582-88-6), 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 RO3 rather than this exact compound?
Yes — that is what the custom synthesis service is for. Send the analogue you actually want instead of accepting RO3 as the nearest listed match, and the team will assess that route.
