Some information from an October 5 UNSC meeting which serves as a useful follow-up to this post from the other day:

Izumi Nakamitsu, Under-Secretary-General and High Representative for Disarmament Affairs, said that, since she last briefed the Council, her Office has maintained regular contact with OPCW and has not received any further information from the Syrian authorities on the implementation of resolution 2118 (2013) — which first mandated the scheduled destruction of the country’s chemical weapons programme.
